func BuildBrokenLinearFunction ¶ added in v1.21.0

func BuildBrokenLinearFunction(shape FunctionShape) func(int64) int64

BuildBrokenLinearFunction creates a function which is built using linear segments. Segments are defined via shape array. Shape[i].Utilization slice represents points on "Utilization" axis where different segments meet. Shape[i].Score represents function values at meeting points.

function f(p) is defined as:

shape[0].Score for p < shape[0].Utilization
shape[n-1].Score for p > shape[n-1].Utilization

and linear between points (p < shape[i].Utilization)

func DefaultNormalizeScore ¶

func DefaultNormalizeScore(maxPriority int64, reverse bool, scores framework.NodeScoreList) *framework.Status

DefaultNormalizeScore generates a Normalize Score function that can normalize the scores from [0, max(scores)] to [0, maxPriority]. If reverse is set to true, it reverses the scores by subtracting it from maxPriority. Note: The input scores are always assumed to be non-negative integers.

func DefaultSelector ¶

func DefaultSelector(
	pod *v1.Pod,
	sl corelisters.ServiceLister,
	cl corelisters.ReplicationControllerLister,
	rsl appslisters.ReplicaSetLister,
	ssl appslisters.StatefulSetLister,
) labels.Selector

DefaultSelector returns a selector deduced from the Services, Replication Controllers, Replica Sets, and Stateful Sets matching the given pod.

func DoNotScheduleTaintsFilterFunc ¶ added in v1.25.3

func DoNotScheduleTaintsFilterFunc() func(t *v1.Taint) bool

DoNotScheduleTaintsFilterFunc returns the filter function that can filter out the node taints that reject scheduling Pod on a Node.

func GetPodServices ¶

func GetPodServices(sl corelisters.ServiceLister, pod *v1.Pod) ([]*v1.Service, error)

GetPodServices gets the services that have the selector that match the labels on the given pod.
